DanLake writes: "On Tuesday, school officials revealed plans to make available the university's entire 1,800-course curriculum by year's end. Currently, some 1.5 million online independent learners log on the MIT OpenCourseWare (OCW) site every month and more than 120 universities around the world have inaugurated their own sites for independent learners. MIT has more than 1,500 course curriculums available online to date.

Carson said MIT's teachers collect what they have created for their courses and make it available over the Web. Many online learners purchase text books for the courses they are monitoring and a recent MIT-Amazon link showed that about 2,000 text books were ordered by independent learners, demonstrating just how serious the learners are.

"Video and audio files are very popular," said Carson. "There are 21 courses with full video available." Typically, independent learners view videos with streaming media players and replay them on PCs, MP3s, or iPods."
